Objectives: Cardiovascular disease (CVD) is associated with a generalized atherosclerotic process that begins in the large arteries, representing vascular pathology leading to increased cardiovascular morbidity and mortality. Pulse wave velocity (PWV) is a simple, accurate, reproducible and a good prognostic marker of arterial stiffness. Testing arterial stiffness with non-invasive techniques provides an opportunity to evaluate large patient populations with cardiovascular risk. Therefore, the aim of the present study was to evaluate non-invasively the arterial stiffness (AS) in patients with high cardiovascular risk. Materials and Methods: Totally 3969 subjects [CAD - 845, DM - 973, ESRD - 942, RA - 221 and 988 age-matched healthy controls] were enrolled in the study approved by the IEC, NIMS; and all the subjects gave written informed consent to participate. Pulse wave velocity was determined non-invasively by PeriScope (M/S Genesis Medical Systems, Hyderabad, India). Results: In patients with CAD, DM, ESRD and RA, heart rate (HR), blood pressure (BP) and PP were significantly more than healthy controls. Peripheral and central arteries' PWVs were higher in these patients' group. The mean HR was maximum in RA patient, while systolic blood pressure (SBP) was highest in ESRD patient. There was a good correlation between ba PWV and PP in all patients' group and healthy controls except RA patients. Conclusion: Our study findings emphasize the importance of the PWV in identifying the vascular damage in patients with high CV risk. Increased PWV was found to be a good independent predictor of cardiovascular morbidity.
